Subject: [PATCH] Fix LoRa presets: true max range BW 62.5kHz/22dBm, shift
 balanced and fast down
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Long Range: SF12, 62.5 kHz, CR 4/8, 22 dBm (~37 bps)
Balanced:   SF9, 125 kHz, CR 4/5, 17 dBm (~1.8 Kbps)
Fast:       SF7, 250 kHz, CR 4/5, 14 dBm (~11 Kbps)

Previous Long Range used 125 kHz (3rd highest BW) and 17 dBm — not
actually max range. SX1262 supports 62.5 kHz BW and 22 dBm TX power.
